CIP Safety in
EtherNet/IP Safety 
Architectures
Safety controllers control the safety outputs. Safety or standard controllers can 
control the standard outputs. Use Guard I/O modules in EtherNet/IP safety 
architectures as shown in Figure 14
. The Guard I/O family is a set of I/O 
modules that when connected to an EtherNet/IP safety network are suitable 
for applications up to and including:
• SIL CL 3 as defined in IEC 61508
• CAT. 4, PLe, as defined in ISO 13849-1
